QUESTION 1 Note: This question is part of a series of questions that present the same
scenario. Each question in
the series contains a unique solution that might meet the stated goals. Some
question sets might have
more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to
it. As a result, these
questions will not appear in the review screen.
You develop a software as a service (SaaS) offering to manage photographs. Users
upload photos to a web
service which then stores the photos in Azure Storage Blob storage. The storage
account type is Generalpurpose V2.
When photos are uploaded, they must be processed to produce and save a
mobile-friendly version of the
image. The process to produce a mobile-friendly version of the image must start
in less than one minute.
You need to design the process that starts the photo processing.
Solution: Convert the Azure Storage account to a BlockBlobStorage storage
account.
Does the solution meet the goal?
A. Yes
B. No
Correct Answer: B

Solution: Move photo processing to an Azure Function triggered from the blob
upload.
Does the solution meet the goal?
A. Yes
B. No
Correct Answer: A
QUESTION 3 You are developing an application that uses Azure Blob storage.
The application must read the transaction logs of all the changes that occur to
the blobs and the blob metadata
in the storage account for auditing purposes. The changes must be in the order
in which they occurred, include
only create, update, delete, and copy operations and be retained for compliance
reasons.
You need to process the transaction logs asynchronously.
What should you do?
A. Process all Azure Blob storage events by using Azure Event Grid with a
subscriber Azure Function app.
B. Enable the change feed on the storage account and process all changes for
available events.
C. Process all Azure Storage Analytics logs for successful blob events.
D. Use the Azure Monitor HTTP Data Collector API and scan the request body for
successful blob events.
Correct Answer: B
QUESTION 4 You are developing a web app that is protected by Azure Web Application
Firewall (WAF). All traffic to the web
app is routed through an Azure Application Gateway instance that is used by
multiple web apps. The web app
address is contoso.azurewebsites.net.
All traffic must be secured with SSL. The Azure Application Gateway instance is
used by multiple web apps.
You need to configure the Azure Application Gateway for the app.
Which two actions should you perform? Each correct answer presents part of the
solution.
NOTE: Each correct selection is worth one point.
A. In the Azure Application Gateway’s HTTP setting, enable the Use for App
service setting.
